Abstract: [Problem] A treatment agent having an excellent ability to remove biofilms and a biofilm treatment method in which the treatment agent is used are provided. [Solution] A biofilm treatment agent characterized by containing at least A1 and/or A2 below. A1: An aromatic monohydric alcohol. A2: An anthranilic acid analog and a biosurfactant. Preferably, the biofilm treatment agent is characterized by containing at least an aromatic monohydric alcohol, an anthranilic acid analog, a biosurfactant, and a synthetic surfactant.

Abstract: The present invention provides a method for determining the physiological state of a microbial community, which rapidly and precisely determines the physiological state of a microbial community present in a treatment tank of a wastewater biological treatment facility; and a wastewater treatment method utilizing the same.

Abstract: According to a vehicular communication system (10) of the present invention, a probe information can be sent to a server (20) from a second vehicle (Q2) out of an arbitrary number of second vehicles (Q2) whose present position is located in a designated area whose information is included in a multicast received by the second vehicle (Q2), in other words, a designated area with high necessity from the viewpoint of leading smoothly a first vehicle (Q1) to a desired position (P2). Also, the probe information can be collected in real time from the second vehicle (Q2) which was present in the designated area in the past and is beyond the designated area at the present time in consideration of the high capability that it holds useful information in estimating the present state thereof in the designated area.

Abstract: According to a vehicular communication system (10) of the present invention, a specified time slot in compliance with one broadcast time slot corresponded to one attribute pertinent to or possessed by a vehicle (1) among a plurality of attributes corresponded to a plurality of broadcast time slots of programs, respectively, according to the broadcast program list. Even though the IGN switch (101) of the vehicle (1) is set at the OFF state, the vehicular communication system (10) is operated or kept at the operating state so as to receive the program broadcasted in the specified time slot.

Abstract: There is provided a safe driving support system that is able to give accurate and appropriate advice to a driver based on the driving conditions at the time the vehicle is actually being driven. A driving conditions collection device receives operation data representing a driving operation and vehicle data representing the behavior of a vehicle and collects these data. A driving trend determination device performs an analysis and makes a determination based on this collected data and extracts any unsafe phenomena. A presentation device then reads, as contents that correspond to the unsafe phenomena in the driving conditions, advice information relating to driving from contents data that have been stored in advance. This advice information is then presented to the driver.

Abstract: A process for judging a runway on a two-dimensional image display presenting image information obtained by taking a picture of the runway. The process comprises, a first step of setting a first window and a second window for scanning and tracing required parts of the runway on the image display, and setting a third window interlocked with the first and the second windows in a set positional relationship therewith, and a second step of, when the third window detects a required part of the runway, setting addition location of the scanning area of the third window to the surrounding area of the required part of the runway.
